TELKOM MOBI IMPOSSIBLE TO CANCEL

I have taken out a TELKOM Mobi account, using it for data purposes. I had the account for nearly 5 years and never skipped a payment. In June 2018 I have decided to cancel this account online. I though I have done it correctly. During this time I also have closed down my bank account. I never had any communication from TELKOM, although they do have my email. I also never received an Invoice. To my surprise I received an email from NUDEBT debt collectors, that I was handed over to them as I was in the arrears for payment. I never have closed my account. I do not have proof of closing down the account and therefore payed the amount that I was in the areas via Pick&Pay, realising that I cannot proof that I closed down by account. Again I tried to closed down the account online, but this is now impossible as my account have been suspended. In the mean while, when I went into my account, I was billed for another month. I already paid this, but my account is still suspended. Going into a TELKOM office, I am told that you can only close down the account ONLINE. This however is not possible as the account is suspended.

I am frustrated, as I do not want this account any more, cannot close down the account online (tried this once before and discovered I was not closed), and I am not assisted in a TELKOM branch to close down the account. In the mean time I get charged every month for something that I do not want.

Is there anyone that can assist me at TELKOM?
